Physical theories, while devised to model a particular range of phenomena, are evidently linked in a hierarchical fashion. It is this structure which keeps fascinating me. In statistical mechanics, my scientific home-town, the link between atomic and macroscopic properties is one central issue. There we are taught that the emergence of a more restricted theory from a more general one has a richer structure than merely letting some parameter tend to infinity. I understood at some point, by accident, that similar issues appear in the dynamics of classical charges coupled to the Maxwell field. Since I could not find a satisfactory discussion in the literature, I decided to write up my own account. |

This book originates from a series of lectures taught to students of aerospace engineering at the University of Manchester over the course of five years. These courses include aircraft performance, aerospace flight mechanics and helicopter theory. In the process, I have taken advantage of other material I have taught in supersonic aerodynamics. Over time, the material grew in scope, to include more advanced research issues of interest to the professional engineer. The book is now proposed as a reference on the subject of atmospheric flight mechanics and performance. The material presented covers a broad range of aspects in aircraft flight, relative to fixedand rotary-wing aircraft. I have excluded from the discussion rockets and re-entry vehicles, which are powered by other means, and operate in transatmospheric flight. These vehicles are the subject of space sciences. |

The American Institute of Physics Handbook has won wide acceptance among scientists and engineers. It is just such a degree of acceptance that has stimulated the issuance of this revised and updated third edition. This edition, like the previous two, continues the philosophy of supplying authoritative reference material-including tables of data, graphs, and bibliographies-selected and described with a minimum of narration by leaders in physical methods for research. Among the entirely new sections in this edition are those on nonlinear optics, calibration energies for alpha particles and gamma rays, nonlinear acoustics, atomic mass formulas, particle accelerator principles, atomic transition probabilities, electric and magnetic fields in the earth's environment, and far infrared. Examples of topics in which especially extensive revisions have been made are: optical masers, various optical constants, virial coefficients, heats of combustion and formation, and superconductors. A number of sections were completely rewritten; these include radioastronomy, radiometry, various crystal properties, molecular constants and hase transitions. The mathematics section now consists of a special treatment of 81 units and a bibliography that has been revised to include references to new methods, algorithms, and computer programs. |

This first book to take a detailed look at one of the key focal points where nanotechnology and polymers meet provides both an introductory view for beginners as well as in-depth knowledge for specialists in the various research areas involved. It investigates all types of application for block copolymers: as tools for fabricating other nanomaterials, as structural components in hybrid materials and nanocomposites, and as functional materials. The multidisciplinary approach covers all stages from chemical synthesis and characterization, presenting applications from physics and chemistry to biology and medicine, such as micro- and nanolithography, membranes, optical labeling, drug delivery, as well as sensory and analytical uses. |

A number of important proteins and enzymes contain copper ions at their active sites. These copper protein sites are associated with a variety of vital biological functions, including oxygen transport and activation, electron transfer, iron metabolism, and superoxide dismutation. The protein ligand imposes an unusual geometric and electronic structure at the copper site. As a consequence, copper proteins often exhibit unique and characteristic spectral features compared to small molecule copper complexes. Studying these spectral features provides insight into the correlation between active site electronic structure and biological function. |

This book is about radio frequency (RF) transceiver system design for wireless communication systems. Most digital communications texts focus on the system design of the digital base-band rather than the RF section. The text is written for RF system design engineers as well as RFIC design engineers involved in the design of radios for digital communication systems. It is also appropriate for senior undergraduates and graduate students in electrical engineering. The text develops systematic design methods of RF receivers and transmitters along with a corresponding set of comprehensive design formulas. Attention is given equally to the analysis of the RF systems. The book is focused on mobile communication systems implemented in RF application specific integrated circuits (ASICs) but it is applicable to other wireless systems such as, for examples, WLAN, Bluetooth and GPS. It covers a wide range of topics from general principles of communication theory, as it applies to digital radio designs, to specific examples on the implementation of multimode mobile systems. It is assumed that the reader has a good RF background, basic knowledge of signal and communication theory, and fundamentals of analog and mixed signal circuits. |

This Report represents the first scientific committee effort by the National Council on Radiation Protection and Measurements (NCRP) devoted solely to radiation protection at nuclear power plants. The members of the Committee represent a mixture of corporate management, operational and regulatory personnel. This Report is another in the series of reports produced under the umbrella of NCRP Scientific Committee 46 on Operational Radiation Safety. There is a wealth of material presented in this Report drawn from the more than 35 years of practical experience in nuclear power operation in this country and Canada. The world's literature on the subject has been reviewed and pertinent material has been incorporated into this Report. The application of the principle of ALARA (as low as reasonable achievable), as promulgated by national (NCRP) and international [International Commission on Radiological Protection (ICRP)] committees, is the central theme and operational examples of its use are provided. |
